C++ 完成一类数据

我应该如何定义基本操作数据？什么是基本操作数据\u标记应答器m\u FODSystemarkTransponder；？是另一个数据填充在基本操作数据中，还是其他数据？ 我看到的是父亲

我想声明一些基本操作数据Mydata1,2,3

来源是

FundamentalOperationalData没有接受1,2,3.的构造函数

您可以使用以下命令初始化此类：

默认构造函数

---

基本操作数据\标记应答器参考

---

基本操作数据（MarkXInterrogator参考） 基本作战资料苏联参考资料 基本操作数据参考 或KDataStream引用

---

FundamentalOperationalData_MarkXTransponder是FundamentalOperationalData类的受保护成员

这里的工会将允许这些成员参与：

通过这些成员

---

因为工会只有足够的存储空间来容纳其成员列表中最大的成员。

是什么阻止了您将某些内容声明为基本操作数据Mydata1、2、3。。。？你有错误吗？您尝试过什么？FundamentalOperationalData_MarkxtTransponder是FundamentalOperationalData类的受保护成员。那么为什么会有FundamtalOperationalData_MarkxtTransponder和struct的联合呢？
